IMPROVEMENT IN CARBURETERS OR HVDROCARBON-DIFFUSERS.

Specification forming part of Letters Patent No. 160,410, dated March 2,1875; application filed October 16, 1874.

To all whom it may concern:

Be it known that I, HENRY J. FERGUSON, of the city and county of NewYork, and State of New York,have invented certain Improvements relatingto Oarbureters or Hydrocarbon-Diiusers, of which the following is aspecification The object of my invention is to provide gas-consumerswith an improved appliance for enriching their gas (as Ordinar-ilysupplied to them) by the use of any of the suitably light hydrocarbons,and also to prevent any oily deposit within the pipes reaching theburners, and hence a danger of confiagration through the act oflighting, Svc.

My invention consists in a vertical cylindrical vessel of suitablethickness and strength of metal, having a detachable cover, to theunderside of which is fixed a spirally-coiled strip of metal, havingattached to it endwise a spirally-coiled piece of felt, or itsequivalent, and termed an absorbent, which, when adjusted with itsappendage, the metallic coil and cover, occupies vertically the chamberof the cylindrical vessel, a given lower portion -of which is alwaysimmersed in the hydrocarbon fluid-that is to say, the chamber of thecylinder is kept filled to a given height with the hydrocarbon uid.

Figures 1 and 2 are vertical longitudinal skeleton sections of thegovernor and hydrocarbon-diiuser in combined relation. Fig. 2 is avertical longitudinal section of ther diffuser or carbureter. Fig. 3 isa horizontal transverse section of the carbureter. Fig. 4 is aperspective view of the diffuser as applied to a chandelier andoperating with it. Fig. 5 is a perspective view of the diffuser,asapplied to a bracket and operating with it.

The same letters refer to the same parts in all the figures.

In Figs. 2 and 3, G is the body of the diffuser, is cylindrical, and hasone side slotted nearly from top to bottom, and to which aninduction-tube, T', likewise slotted, is joined, slot to slot, so as toform a lengthened passage between the two parts. Joining T at the bottomby a horizontal tubular connection is a vertical tube, T", for supplyingthe vapor fluid. c is its closer. T may be of glass, and thus serve asan indicator, too,'to the quantity of contained vapor iluid, the latteroccupying any practical level, as Z. V is a detachable cover of theinstrument, in the center of which is a neck to connect with coupling P,and to join the eduction-tube T, and in it, too, over T, is also anotherneck, P, to join the meter-connection P. R, Figs. 2 and 3, are verticaland transverse sections of the interposed leather, lead, or otherequivalent, (lead is preferable, because of its perfect rlexibility andhigh gravity,) the use of the latter quality in the lower end of thecoil being to keep the planes of the coil in even and perfect shape byweighted stretching, and thus avoid the use of all interferingsubstances, as wire-cloth and the like, it being desirable that thepassing gas should have the widest contact, and an unobstructed passagealong the planes of the coil. The upper interpose or strip R is themedium for attaching'the absorbent coil to the detachable cover V, theattachment being made by passing screws through cover V, and into It,the upper interpose being attached to the under side of cover V. j,Figs. 2 and 3, are vertical and transverse sections of the felt coil.Gas from the meter traverses the interspace of the felt coil above thesurface of the vapor fluid from T', goes out at T, then on through A,dto.

It will be seen that the absorbent coil will steadily elevate anddiffuse through its substance the vapor fluid, and that, as gasprogressively advances along the wet planes of the coil, it will moreand more take up and become charged with vapor, and the degree ofcharging or saturation may be estimated by the distance traveled by thegas through the felt coil, or by the equivalent length of it. Thus thedegree of diffusion may be regulated, and it may also be regulated bythe depth of the vapor-space maintained, or,in other words, by thedistance the level of the vapor iluid is maintained from the top of thechamber.

The width of It determines the width of the interspace, and is thus oneof its special uses, constructively, and as respects the necessaryvolume of space the respective volume of gas requires.

In adapting the diffuser in miniature to chandeliers and brackets,various ornamental forms may be employed, and generally in those Casesthe gas enters by the center, or cenmaterial, provided with detachablestrips of trally, and passes out by the periphery. heavy metal at eachend7 and secured to the I do not claimahydrooarbon-clifi'user,broadcover, substantially as herein shown andset Y ly; but forth.
